STEVAL-IHT001V1演示板是采用双极型晶体管的完整参考系统的简单经济高效的PFC（功率因数校正）和适用于低功耗tomedium高频镇流器。The STEVAL-IHT001V1 demonstration board is a complete reference system for a simple costeffective PFC (power factor corrector) using bipolar transistors and is intended for low-tomedium power HF ballasts.The proposed bipolar PFC solution targets the low-cost HF ballast market up to 80 W as it provides a simple cost-effective solution without sacrificing THD and PF levels. No additional ICs are required for the PWM signal as the device uses just a power bipolar transistor and a closedloop feedback which performs the duty cycle modulation and output power regulation.The active PFC solution with bipolar transistor adopts the boost topology operating indiscontinuous-conduction mode.
